Acute Pancreatitis in COVID-19-associated Multisystem Inflammatory Syndrome of Children-A Single Center Experience.

ABSTRACT: A multisystem inflammatory syndrome in children (MIS-C) was identified as an entity temporally associated with the present COVID-19 pandemic. This inflammatory syndrome affects various organ systems including the gastrointestinal and hepatobiliary systems. The following study was undertaken to primarily detect the fraction of children who had pancreatitis as major organ involvement during the development of MIS-C. The secondary objective was to evaluate their clinical and investigational profile as well as the outcome of management.

Methods

A retrospective chart analysis of all children admitted in a tertiary pediatric center from April to December 2020, diagnosed as COVID-19 associated MIS-C, was done. Those presenting with acute pancreatitis were detected and detailed clinical features, investigations, treatments, as well as outcomes, were recorded.

Results

A total of 17 children were diagnosed as MIS-C associated with SARS-CoV-2 in the above-mentioned period. Among them, 9 (53%) children had pancreatitis right from the start of the illness; 5 (56%) children with pancreatitis presented with shock. A very high CRP and cardiac involvement were observed in all. A severe reduction of myocardial contractility was associated with poor outcomes. Necrotic pancreatitis was not noted in any of them. A mortality of 22% was documented in this group and a 3-month outcome among those who survived displayed complete resolution of all cardiac as well as pancreatic abnormalities.

Conclusion

Acute pancreatitis can be an essential cause of abdominal symptoms in COVID-19-related MIS-C. Pancreatitis may be considered to be one of the parameters in the diagnostic criteria of MIS-C.

Project description:Background and aims:A newly recognized multisystem inflammatory syndrome in children (MIS-C) has had a paradigm-shifting effect on the perception of severe acute respiratory syndrome, coronavirus-2 (SARS-CoV-2) illness severity in children. We report the clinical and biochemical features of liver involvement, and the comorbidities that present with hepatitis, in a substantial cohort of patients.Approach and results:This is a retrospective cohort study of 44 patients with MIS-C admitted at Morgan Stanley Children's Hospital of New York-Presbyterian during April and May 2020. We evaluated the number of patients who developed hepatitis and examined both demographics and inflammatory laboratory values to ascertain those that were at higher risk for liver involvement and more severe disease. Hepatitis was present in 19 subjects (43%) and was associated with more severe disease. Persons with hepatitis had significantly higher rates of shock at presentation (21.1% vs. 0%; P = 0.008), greater respiratory support requirement (42.1% vs. 12%; P = 0.005), and longer hospitalization times (median, 7 [interquartile range {IQR}, 5, 10] vs. 4 days [IQR, 3.5, 6.5]; P < 0.05). Patients with hepatitis also had significantly higher levels of ferritin (706.9 vs. 334.2 mg/mL; P < 0.01), interleukin-6 (233.9 vs. 174.7 pg/mL; P < 0.05), troponin (83.0 vs. 28.5 ng/L; P < 0.05), and B-type natriuretic peptide (7,424.5 vs. 3,209.5 pg/mL; P < 0.05). The single patient with liver failure also developed multiorgan failure requiring vasopressors, hemodialysis, and mechanical ventilation. All patients were discharged, though >50% had persistent hepatitis up to 1 month after discharge.Conclusions:Hepatitis is common in children with MIS-C and is associated with a more severe presentation and persistent elevation of liver function tests in many. Despite the positive outcomes reported here, close follow-up is warranted given the limited knowledge of the long-term impact of SARS-CoV-2 on the liver.

Project description:ImportanceMultisystem inflammatory syndrome in children (MIS-C) is a severe and unrestrained inflammatory response with multiorgan involvement, which occurs within a few weeks following the resolution of acute SARS-CoV-2 infection. The complement system is a vital part of the innate immune system and plays a role in COVID-19 pathogenesis.ObjectiveTo examine and compare the levels of complement components and regulators along with complement activation products in the different clinical spectrum of children with SARS-CoV-2 and a control group.Design, setting, and participantsThis cross-sectional study analyzed children with MIS-C admitted to a single hospital in India from June through September 2020. Eligible participants were children who were hospitalized of either sex, aged 1 to 18 years. Data were analyzed August 2022.MeasuresLevels of complement components and regulators along with complement activation products in all the groups of children. Mann-Whitney U test and Kruskal-Wallis analysis were used to compare the complement component levels, and Spearman rank correlation analysis was used to describe the association between complement components and laboratory and biochemical parameters.ResultsA total 145 children were included (median age, 5 years [range, 1 month-17 years); 84 [58%] male): 44 children with MIS-C, 33 with acute COVID-19 (reverse transcriptase-polymerase chain reaction [RT-PCR] positive), 47 with convalescent COVID-19 (immunoglobulin G-positive non-MIS-C) and 21 children for a control group (both serology and RT-PCR negative). Children with MIS-C and COVID-19 had higher levels of C1q (geometric mean [SD]: MIS-C, 61.5 [18.5] ng/mL; acute COVID-19, 56.9 [18.6] ng/mL; controls, 24.1 [3.3] ng/mL), C2 (MIS-C, 605.8 [219.7] ng/mL; acute COVID-19, 606.4 [167.7] ng/mL; controls, 255.9 [73.3] ng/mL), C3 (MIS-C, 318.2 [70.7] ng/mL; acute COVID-19, 237.7 [61.8] ng/mL; controls, 123.4 [15.7] ng/mL), C4b (MIS-C, 712.4 ng/mL; acute COVID-19, 640.7 ng/mL; controls, 351.5 ng/mL), C5 (MIS-C, 1487 ng/mL; acute COVID-19, 1364 ng/mL; controls, 561.9 ng/mL), C5a, (MIS-C, 2614.0 [336.2] ng/mL; acute COVID-19, 1826.0 [541.0] ng/mL; controls, 462.5 [132.4] ng/mL), C3b/iC3b (MIS-C, 3971.0 [635.1] ng/mL; acute COVID-19, 3702.0 [653.9] ng/mL; controls, 2039.0 [344.5] ng/mL), and factor B (MIS-C, 47.6 [7.8] ng/mL; acute COVID-19, 44.6 [6.3] ng/mL; controls, 27.5 [5.0] ng/mL), factor D (MIS-C, 44.0 [17.2] ng/mL; acute COVID-19, 33.8 [18.4] ng/mL; controls, 21.3 [6.1] ng/mL), and factor H (MIS-C, 53.1 [4.0] ng/mL; acute COVID-19, 50.8 [5.7] ng/mL; controls, 43.6 [3.8] ng/mL) in comparison with convalescent and control children. In addition, children with MIS-C had significantly elevated levels of C3 (318.2 [70.7] ng/mL vs 237.7 [61.8] ng/mL), C5a (2614 [336.2] ng/mL vs 1826 [541.0] ng/mL), and mannose-binding lectin (79.4 [12.4] ng/mL vs 69.6 [14.7] ng/mL) in comparison to children with acute COVID-19. Levels of some of these analytes at admission (ie, pretreatment) were more elevated in children with MIS-C who needed pediatric intensive care unit (PICU) support as compared with those who did not require PICU support, and in children with COVID-19 who developed moderate to severe disease compared with those who developed mild disease. Overall, MIS-C and acute COVID-19 were associated with the hyperactivation of complement components and complement regulators.Conclusions and relevanceIn this cross-sectional study, the complement system was associated with the pathogenesis of MIS-C and COVID-19 in children; complement inhibition could be further explored as a potential treatment option.

Project description:BackgroundAlthough most children experience mild symptoms during acute SARS-CoV-2 infection, some develop the severe post-COVID-19 complication, Multisystem Inflammatory Syndrome in Children (MIS-C). While acute presentations of COVID-19 and MIS-C have been well immunophenotyped, little is known about the lasting immune profile in children after acute illness.MethodsChildren 2 months-20 years of age presenting with either acute COVID-19 (n = 9) or MIS-C (n = 12) were enrolled in a Pediatric COVID-19 Biorepository at a single medical center. We deeply profiled humoral immune responses and circulating cytokines following pediatric COVID-19 and MIS-C.ResultsTwenty-one children and young adults provided blood samples at both acute presentation and 6-month follow-up (mean: 6.5 months; standard deviation: 1.77 months). Pro-inflammatory cytokine elevations resolved after both acute COVID-19 and MIS-C. Humoral profiles continue to mature after acute COVID-19, displaying decreasing IgM and increasing IgG over time, as well as stronger effector functions, including antibody-dependent monocyte activation. In contrast, MIS-C immune signatures, especially anti-Spike IgG1, diminished over time.ConclusionsHere, we show the mature immune signature after pediatric COVID-19 and MIS-C, displaying resolving inflammation with recalibration of the humoral responses. These humoral profiles highlight immune activation and vulnerabilities over time in these pediatric post-infectious cohorts.ImpactThe pediatric immune profile matures after both COVID-19 and MIS-C, suggesting a diversified anti-SARS-CoV-2 antibody response after resolution of acute illness. While pro-inflammatory cytokine responses resolve in the months following acute infection in both conditions, antibody-activated responses remain relatively heightened in convalescent COVID-19. These data may inform long-term immunoprotection from reinfection in children with past SARS-CoV-2 infections or MIS-C.
